A trapezoid is shown:

What is the area of the trapezoid?

Answers

Answer 1

Answer:

Answer:

Area of trapezoid is:

162 cm²

Step-by-step explanation:

Area(A) of trapezoid is given by:

$A=(1)/(2)* (sum\ of\ parallel\ sides)* (Height)$

Here, we are given Height=9 cm

One parallel side=6 cm

Other parallel side=(12+6+12) cm

= 30 cm

Sum of parallel side=(6+30) cm

= 36 cm

Area= $(1)/(2)* 36* 9$

= 162 cm²

Hence, Area of trapezoid is:

162 cm²

Answer 2

Answer: A = 1/2(6+30)(9)
A = 1/2(36)(9)
A = 162
answer
162 cm^2

Answer:

66 2/3 %

Step-by-step explanation:

First find the students not in the 8th grade

24 - 8 = 16

16 students are not in the 8th grade

Take the fraction of the students not in the 8th grade over the total

16/24 = 2/3

Change to a decimal

.66666666666

Multiply by 100 to change to a percent

66.666666%

66 2/3 %

Answer:

66.67% of students are not in eighth grade

Step-by-step explanation:

8/24=1/3

1/3=0.33333333333

1-0.33333333333=0.66666666667

0.66666666667=66.67%

Find the measures of the supplementary angles that satisfy each case.The measure of the first angle is 45° more than the measure of the second.
(I will make you braniliest if it is correct)

Answers

Answer:

67.5°, 107.5°

Step-by-step explanation:

For supplementary angles, their sum equals 180°.

Let x be the first angle and y be the second angle, then

x + y = 180°.

It is given that x = y + 45°.

So x + y = 180°

substituting x into the equation, we have

y + 45° + y = 180°

simplifying, we have

2y + 45° = 180°

collecting like terms, we have

2y = 180° - 45°

2y = 135°

dividing through by 2, we have

y = 135°/2

y = 67.5°

Since y = 67.5°

then x = y + 45°

x = 67.5° + 45°

x = 107.5°

Final answer:

The measures of the supplementary angles that satisfy the given conditions are 67.5° and 112.5°.

Explanation:

Let's say the measure of the second angle is x. Since the measure of the first angle is 45° more than the measure of the second, we can express the first angle as the measure of x + 45°.

By the definition of supplementary angles, we know that the sum of the measures of two supplementary angles is 180°. Therefore, we can create the following equation: x + (x + 45) = 180.

Solving this equation gives us:

Add the expressions on the left side of the equation to get: 2x + 45 = 180.
Subtract 45 from both sides of the equation to isolate the term containing x: 2x = 135.
Divide both sides of the equation by 2 to solve for x: x = 67.5°.

So, "the second angle measures 67.5°, and the first angle, being x + 45°, measures 112.5°".

In the game of tic-tac-toe, if all moves are performed randomly the probability that the game will end in a draw is . Suppose six random games of tic-tac-toe are played. What is the probability that at least one of them will end in a draw?

Answers

Completed question:

In the game of tic-tac-toe, if all moves are performed randomly the probability that the game will end in a draw is 0.127. Suppose six random games of tic-tac-toe are played. What is the probability that at least one of them will end in a draw?

Answer:

0.557

Step-by-step explanation:

For each game, the probability of not end in a draw is 1 - 0.127 = 0.873. Thus, because each game is independent of each other, the probability of all of them not end in a draw is the multiplication of the probability of each one:

0.873x0.873x0.873x...x0.873 = 0.873⁶ = 0.443

Thus, the probability that at least one of them end in a draw is the total probability (1) less the probability that none of them en in a draw:

1 - 0.443

0.557
